NUT LOCK.

m Application filed July 18, 1984. ySerial No. 726,814.

To all whom t may concern:

Be it known that we, HENRY J. VAN GELDER and Jol-IN VARD, citizens ofthe United States, and residents of the city of New York, borough ofBrooklyn, in the county of Kings and State of New York,

have invented a new and Improved Nutv Lock, of which the following is` afull, clear, and exact description.

This invention relates to improvements in nut locks, and has for one ofits objects the provision of a nut lock of simple and inexpensiveconstruction which will effectively prevent displacement of the nut fromits adjusted positions, and in which the threads of the various partswill be protected against moisture and the accumulation of dirt and gritthereon.

The above and other objects willV appear more clearly from the followingdetailed description, when taken in connection with the accompanyingdrawing, which illustrates preferred embodiments of the .inventive idea.

In the drawing Y Figure 1 is a fragmentary longitudinal section oianother form of the invention; and

Figure 2 is a section on the line 2-2 of Figure 1.

The lock of, the present invention is applicable to various uses, amongwhich may be mentioned its adaptation as a part of the mechanism foradjusting brake rods and the like. It will be appa-rent, on reference tothe drawing that the device of the present invention includes a member21 on the head ot which is an extension 23, which, at its outer endterminates in an externall screwthreaded portion 9. The member" 21including its extension 23 is formed with a longitudinal bore or opening12. Preferably at diametrically opposite points the eX- tension 23 issplit longitudinally, as indi-y cated at 13, throughout its entirelength.

The device also includes an adjusting member 24 formed with a head fromwhich extends an internally-screw threaded sleeve 25 slottedlongitudinally, as indicated at 26, and capable of being inserted intothe bore 12 in said extension 23 of the member 21.

The internal threads of the sleeve are capable of receiving a threadedrod 27 which carries a clevis 28 at its outer end and with respect towhich the member 24 is adjustable to vary the effective length ot therod 2T. To permit of adjustment of the member 24: a portion 2!) of thehead thereof is extended beyond the adjacent end of the locking member30, and formed to receive a wrench or other tool by means of which themember 24 may be rotated in either direction to a1:- complish thedesired adjustment. Vhen this is attained the memberEO, which haspreviously been unscrewed slightly to disengage its tapered surface fromthe tapered surface of the extension 23, vmay then be screwed home tothe position shown in the Y drawing whereupon the inturned fiange 31 ofthe member 30 will engage the head oi the member 24 and thereby securethel latter member in its adjusted position. By forming the sleeve 25with slots the sections of said sleeve will be caused to tightly gripthe threads of the rod 27 by yreason of the pressure on theextension 23when the locking member 30 is` adjusted to its locking position shown inthe drawing. Also the slotted foru mation of the sleeve 25, whichpermits oi its being contracted into engagement with the threads of therod 2T, will overcome any variations in the diameter oli' the threads ofsaid rod.

lVhat is claimed is: A device of the class described.y including alongitudinally slotted member, a slotted adjusting member insel-tableinto the firstnamed member and capable of being mounted upon a rod tovary the effective length of said rod, and a locking member engageablewith said adjusting member and mounted upon the lirst-nanied member andoperable to compress the slotted portion of said adjusting member intoengagement with said rod through the intermediary of lt)he slottedportion of said first-named inem- HENRY J. VAN GELDER. JOHN WARD.
